description
Composition. Trichocerinae Rondani, 1841, Paracladurinae Krzemińska, 1992, Kovalevinae Krzemińska, Krzemiński et Dahl, 2009 and Ewauristinae subfam. nov.
diagnosis
Revised diagnosis. Tipulomorpha with distinct basal R and M bends opposed at atrophied MA (= arculus), 1 A (2 A of traditional system) shortened (its distal portion often subtransverse), ocelli developed, scutoscutellar suture obscure, and female cerci (when elongate) curved downwards. Pedicel somewhat enlarged, larger than scape, usually contrasting to setaceous flagellum (except for some Jurassic genera with moniliform antennae).
discussion
Remarks. The following characters, not found in the new genus, could no more be considered as diagnostic for Trichoceridae: crossvein sc-r in proximal position, R with 3 long branches, and R 2 crossvein-like near the R 3 base. In fact, R 2 is not proximal also in several other trichocerid taxa: it is equidistant between R 2 + 3 origin and R 1 apex in a few species, or even slightly nearer to the R 1 apex in modern Nothotrichocera antarctica (Edwards, 1923) and Jurassic Mailotrichocera jurassica Kalugina, 1985 (Krzemińska 2001: fig. 20; Krzemińska, Krzemiński et Dahl 2009: fig. 19 B).
